Operator Upgrade

Upgrading Drivers with Dell CSM Operator

You can update CSI Drivers installed by the Dell CSM Operator like any Kubernetes resource:

Get the driver-object details using kubectl command:

kubectl get csm -n powerstore

kubectl get csm -n isilon

kubectl get csm -n vxflexos

kubectl get csm -n powermax

kubectl get csm -n unity

As of CSI PowerMax v2.14.0, the csi reverse proxy configuration and connectivity information has been migrated from a ConfigMap to a Secret. If the powermax-creds secret format was not previously updated, reference Step 2 in CSI Driver installation steps.

Set the authSecret to the name of the secret created, powermax-creds. Also, set X_CSI_REVPROXY_USE_SECRET: true in your CSM file to use the new secret configuration.

Note: The powermax-reverseproxy-config remains for backward compatibility only. Use of the powermax-creds Secret, as outlined above, is recommended.

If you would like to continue using the powemax-reverseproxy-config ConfigMap, set X_CSI_REVPROXY_USE_SECRET: false in your CSM file, and skip the creation of this Secret.

Additionally, the powermax-array-config is deprecated and can be deleted. Its values have been migrated to Powermax sample.

To continue using powermax-array-config, follow Step 3 in the CSI Driver installation steps. If not using it, add values to X_CSI_MANAGED_ARRAYS, X_CSI_POWERMAX_PORTGROUPS, and X_CSI_TRANSPORT_PROTOCOL in the sample yaml.

Note: powermax-array-config is kept for backward compatibility only.

Use the object name in the kubectl edit command:

kubectl edit csm powerstore -n powerstore

kubectl edit csm isilon -n isilon

kubectl edit csm vxflexos -n vxflexos

kubectl edit csm powermax -n powermax

kubectl edit csm unity -n unity

Modify the installation as needed, typically updating driver versions, sidecars, and environment variables.

Refer how to upgrade guide if you have more questions

Warning

Starting with CSM 1.12, all deployments will need to use images from quay.io . Please note that from CSM 1.14 (May 2025), upgrading will fail if it attempts to use images from Docker Hub.

Supported modifications

Changing environment variable values for driver
Updating the image of the driver
Upgrading the driver version

NOTES:

If you are trying to upgrade the CSI driver from an older version, make sure to modify the configVersion field if required.
```
   driver:
     configVersion: Default text if no valid parameter is passed.
```

Warning

Don’t update the original CustomResource manifest file with kubectl apply -f. It can overwrite important annotations and cause failures.
